Having some issues with my new toy, MC21 SP
The powervalves were not moving at all I noticed when changing the coolant and blipping the throttle
I did the test by disconnecting the tps and turning the bike on to see if the servo moves to high position but it stayed put, battery output 12.49v
I checked at the pgm unit harness on the harness side the BU/G-Y/R and it was within range (was 5ohms)
I checked between BU/G-Y/BU for resistance as I moved the throttle and was within range, so I can safely assume the tps is fine.
I tested the servo motor at the connector by applying voltage and it moves, also checked resistance between LG connector and the BU/G on the connector and fluctuates between 0 and 4.6 or so as the servo cycles.
now that the cables are off the servo I checked the movement of the valves by hand and they move freely
Next step was to check continuity between the black harness connector and the servo connectors...all good so harness is fine..
Output voltage at servo motor, ignition on kill switch on is 4.59v, seems fine...
Voltage at tps connector is 4.5
My manual says to check the output voltage from the black harness connector on the B/W to ground with ignition on and kill switch OFF, page 24-67. Says I should get battery voltage with switch off....I do when i put kill switch to run....but no voltage when switch is off....seems weird to me.
Anyway, what can I do ....what haven't I done?
